Vertical Bead Mill Gains Power

Hytec Johannesburg has joined forces with Deswik Mining Consultants. This comes after Hytec signed a contract to supply hydraulic power packs and motors for use on Deswik’s vertical bead mills.

The Deswik 1000 litre mill is capable of grinding in excess of 30 dry tons of ore per hour, from input particle sizes of between 150 to 45 microns, to outputs of between 38 to 5 microns. The entire drive and milling system is automated and PLC-controlled.

In comparison to the standard electric motor/gearbox drive, this new solution offers significant saving of the installed power requirement. The advantage of the hydraulic drive is the ability to deliver full torque at start-up.

The development of the Deswik vertical bead mill started in early 1998, with the first commercial unit being supplied in 2000. Since its inception, the new design has surpassed all expectations and has proven to have many benefits including, lower energy costs, greater reliability, ease of maintenance, better heat dissipation, smaller footprint, low operating– costs, superior grinding quality and a significantly shorter lead time.

This uniquely designed patented mill with stepless speed control and full torque over the whole range, will produce the desired product by balancing the closed loop speed control and bead load.
